Hoest: HAY-RARE.`

SPECIFICATION forming part of Letters Patent No. 278,538,` dated May 29, 1883,

I Appleman inea Mayu; 1879.

Be it known that I, MARTIN HALLENBEGII,

'of Albany, in the county of Albany and State ot' New York, have invented certain new and useful Improvements in HorseHay-Rakes, ot' which improvements the following. is a speciiication, reference being had to the accompanying drawings, which make part thereof.

1t is the object ot' my invention to provide a simple and effective automatic device for raising the teeth of a. horse hay-rake from the wi th an automatic devicefor lowerin g the rakeground at intervals, as required, jto discharge ,the gathered hay, to bey used in connection teethafter the gathered hay has been dis charged, so that the driver has only to determine the intervals between the discharges, and is relieved from the laborot' liftingand lowering thc teeth; and to these ends my'invention consistsin combining with a two-wheel horse hay-rake a device which I designate as a switch, the operation otfthc switch being such that the driver by moving a lever sets theswitch, and the forward movement ot' the machine raises the teeth, so as todischarge the gathered hay, when a trippingfhorn, at the propermoment, releases the rake-teeth and permits them to resume their gathering position.

In theaccompanying drawings I have shown `myimprovements applied to a twowheel horse hay-rake, having a frame upon which the rake head or bar to which the rake-teeth are aty tached is mounted in pivoted bearings, the

` ecured to v down; Fig. 4,a similar viewot' the same, also inverted, showing the position ot' the parts when set for raising the teeth; and Fig. 5, aV

vertical central section through the switch,the parts being in the position shownby Fig. 3.

So far as regards the rgeneral construction of themachin, the details may be varied; but the teeth,however secured,must be connected to a rocking head, A, whichextends across the frame and to withina short distance of each of the ratchet-rings B, interposed between the carrying-wheels C and the ends of the The switch is mounted centrally on the head A, and the switch-rods E extend along the rake-head from points within the case ot' the switch to points slightly beyond the ends ot' the head A, the inner ends otvthese rods being 6o operated as hereinafter described, and their outer ends, which l.1ct aslocking-pawls, being guided in boxes F, secured on the ends o'tthe head A, which boxes alsosupport the pawl ends ot the rods wbenengaged with the teeth 65 of the rings B. These movements ot' the rods E are effected by means of the lever G and y lilik H, connecting the lever with the switchblock, the rods being moved outward or pro` truded by the driver pushing the lever Gaway 7o` lfrom the switch-case, and the withdrawal ot' the rods being automatically effected by the trippiuglhorn I, located upon the frame ot the machine at'the proper point and adjusted for tripping the lever at theproper time. These 75 rods E act 'independently ot each other, thereby permitting the apparatus to work on curves-1' without tripping the pawls prematurely.

The switch is composed ot' a cast-iron box, v a, having a circular center with tubular pro- 8o jections, the circular center being open in front, and the tubular projections having openings at their ends, and the two parts ot the box being` secured together by bolts and nuts. The inner face of the bed plate or bottoni of the 85 box is simply provided with suchdepressions orlrecesses and projections or iiangesaswill inclose thoseV parts of the mechanism which project beyond the'surfaces of the upper part of the case, as shown in Fig. 5. Thev upper 9o part of the box a-has a circular recess, across which a longitudinal groove, b, extends from end to end ot' the box. In `the center ofthis groove is a socket, c, and along the back ot' Athe circular recessris a steel spring, c', which 95 performs the function ot' holding the switchblock in either of the positions showpl in Figs.

`3` and 4, the bearing of the spring ii Fig. 3

being, as shown, such as to prevent any tendency ot' the switch-block to be swung on its roo center byjolts or inclinations'ot the machine,

as but for the springit would be, and in the position shown inv Fig. 4 thespring serves as e'ectually to prevent` the switch from being s v erases tripped by similar causes, and keeps it in pois tripped'. Cast-iron troughs e c4 are fitted into the groove b', on each side of the socket, the troughs having uprightpins ff in them, spaces being left between these pins and the ends ofthe troughs, in which spaces the switchblock lits; as presently to be described. The

ra outer ends of the troughs have openings corresponding with the open ends ot' the case a. The troughs must be jtted in the groove, so

as to slide freely along it.. Each ofthe switchrods E has a collar, E', near its inner end, and

x5 this end'ot' the rod lies in the trough e, with the collar against the sides ofthe opening in thetrough,whereit is held bya coiled spring, g. The switch-block d, Figs. 3, 4, and 5, is cast in the form shown in the drawings, with pins zo d d2 on its respective sides, and slots d3 d4,

curved in opposite directions on each side'ofl the center-pins d d2. The front of the switchblock'is prolonged, so that it 'will protrude `through the opening in the center ofthe case,

I z5 and the block rests in the central circular recess of the case, with the pin d in the socket o, the pin d2 having a corresponding bearing in the bed-plate, whilethe slot cl3 tits over the 4pin f, and the slot di over the pin j". This 3o position of these parts is shown in Figs. 3 and 5, in which' it will .be seen that the switchblock restsn pon the iace of the circular recess',

its front protruding through the opening, and

#its center being pivoted in the socket and in the bed-plate, its back edge being borne upon rbythe spring c' while the troughs are ldrawn hack in the groove, and held close to the socket in the curved slots d3 d4, the rods E bcing retracted correspondingly, so that their 4o pawl ends donot engage with the teeth on the rings B.

l '1he change of position necessary for protrnding the-rods and engaging their pawl ends with the teeth in the rings B is shown in Fig.

4, and this change is effected by swinging the yswitch-block on its centeraoross the opening in the front of the cased, with which movement the pinfmoves along the curved slot d3 y and the pin f along the curved slot d, sliding 5o the troughs along the groove away from the center and protruding the rods E, so that their pawl ends engage with the teeth in the rings B. This last described movement of the switch-block is effected through the lever .G

and link-rod H4 by the driver, as already described. -t-,When thus protruded and engaged with the teeth of the rings B, the pawl ends of the'rods E ot' course lock the rakehead to t-he'carr'ying-wheels, so that with the further 6o advance'of the machine the rake head is turnedon its pivots, raising the teeth, and lto disengage theteeth at the desired point in this revolution the tripping-horn I is so located 'updnv`- Vthe frame of the machine that a small 65 rriction-rollerupon the side of the lever will strikevupon and follow'the inclined surface of the `tripping-horn unt-il the lever is thrown back toward the driver, thereby reversing the switch-block and restoring the parts to the positionl shown in Fig. 3, withdrawing the pawl ends from the rings andallowing the teeth to drop, as already described.

For cases in which itis desirable to hold the teeth in an elevated position when the pawls are not engaged with the rings B, I attach a loop, K, to the rake-head and a pivoted brake,

L,tothe frame, so that the driver, by turning the rake-head up and holding the brake against. the loop with his foot, can keep the teeth suspended, and by reversing the brake, so that it shall bear against the loop when the teeth are down, the driver can hold the teeth down to the ground while the pawls are not engaged with the rings.

Having thus described the nature and objects ot' my invention, what I` claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a horse hay-rake, of the carrying wheels provided with toothed rings, the pivoted rakehead provided with rake-teeth, the pivoted and slotted block, the switch-rods having ai connection with the slots in the switchblock,and their outer ends adapted to directly engage the toothed ring and the lever pivoted onv the rake-head for rotating the switch-block to cause the switch-rods to engage the toothed rings and rotate the rakehead, substantially as described.

2. The combination, in a horse hay-rake, of the carrying wheels provided with toothed rings, the pivoted rake-head, the pivoted switch-block havingoppositely-curved slots, the switch-rods both operated by the one 'switch-block, and a spring acting upon said block to hold 'it in either of its adjusted posi tions, substantially asi described.

3. The combination of the carrying-wheels provided with toothed rings, the pivoted rakehead, the switch-block, the troughs, the coiled springs in the troughs, and the switch-rods IOO IOS

IIO

having collars against which the outer ends of the coiled springs bear, substantially as described.

4. The combination of the switch-box having recesses in its bottom plate, the slotted switchblock, the troughs having pins projecting through the block into the recesses in the bottom plate of the switch-box, the switchrods, and the coiled springs lin the troughs, substantially as described.

5. The combination of the slotted switchblock, the troughs, the coiled springs within the troughs, and the switch-rods, substantially as. set forth.

6. The combination of the carrying-wheels, the toothed rings, the pivoted rake-head, the

slotted' switch-block, the troughs, the coiled springs within the troughs, the switch-rods,

and the lever for operating'the switch-block.
